Cpu: Implement VCVT (between floating-point and fixed-point) instruction (#5343)

* cpu: Implement VCVT (between floating-point and fixed-point) instruction

Rebase, fix and superseed of https://github.com/Ryujinx/Ryujinx/pull/2915

(Since I only have little CPU knowledge, I hope I have done everything good)

* Update Ptc.cs

* Fix wrong cast

* Rename tests

* Addresses feedback
